Hmm, okay well it worked in the sense that I can adjust the number of decimal places saved (e.g. I tried format("%.1f", Channel0.Time) ﻿ and got 1 decimal place).
But when I tried format("%.6f", Channel0.Time) I still only got 3 decimal places, which leads me to believe that the Channel0 is only generating 3 decimal places so there's nothing to show beyond 3. I looked into the Channel settings to see if I could specify the number of decimals, but didn't see anything.
Is there a way I can specify that Channel0 saves up to 4 decimal places?
Thank you!

Now that I'm saving data directly to file, I'm trying to figure out how to save the time points with microsecond precision.
I see from the manual the the data logging (which I was previously using) has the option to change the Sig Figs:
" Time Sig Figs: Determines how many significant figures are used to write time values. A value of 9 yields timeprecise to the second, 12 to the millisecond and 15 to the microsecond. The maximum value is 15. "
But now that I'm using the File.WriteDelim function to save my data, how do I specify that I want the time to be saved with 14 sig figs?
Thank you!

Hello there!
I'm trying to log data for 10 seconds every 10 minutes - each 10 seconds of data saved to its own separate file.
So I have 2 problems with my script pasted below:
1) For some reason the file will have the first 6 or 7 seconds of data and not the entire 10 seconds
2) but even more annoying is that when the 10 minutes is up and it is supposed to switch to a new file, for some strange reason it records the first second or two in the previous file before finally making the switch to a new file. It's like it starts logging in the file from 10 minutes ago for a second or two before finally opening a new file to begin logging.
I've tried troubleshooting this in a variety of ways but still have been unable to get 10 seconds of data to save in its own file every 10 minutes.
Any help is appreciated, thank you.
Logging.DataLog.FileName = "D:\ALT DAQFactory Saves\ALT_" + formatDateTime("%y%m%d_%H%M%S", systime()) + ".csv"
beginlogging(DataLog)
// Loop to read stream data and append it to the DF Channels.
while(1)
dataIn = LJM_eStreamRead(identifier)
if (systime() <= timestamp + 10) // If the first 10 seconds of every 10 minutes, log the data - otherwise don't read the data
data = insertTime(dataIn.data.AIN0, st, 1 / scanRate)
Channel0.AddValue(data) // Needs to match channel defined in "Channels".
data = insertTime(dataIn.data.AIN1, st, 1 / scanRate)
Channel1.addValue(data)
data = insertTime(dataIn.data.AIN2, st, 1 / scanRate)
Channel2.addValue(data)
data = insertTime(dataIn.data.AIN3, st, 1 / scanRate)
Channel3.addValue(data)
data = insertTime(dataIn.data.AIN4, st, 1 / scanRate)
Channel4.addValue(data)
data = insertTime(dataIn.data.AIN5, st, 1 / scanRate)
Channel5.addValue(data)
data = insertTime(dataIn.data.AIN6, st, 1 / scanRate)
data = data*55.45 - 17.78 // Convert channel voltage from mV to degrees C
Channel6.addValue(data)
data = insertTime(dataIn.data.AIN7, st, 1 / scanRate)
data = data*55.45 - 17.78 // Convert channel voltage from mV to degrees C
Channel7.addValue(data)
endif
if (systime() >= timestamp + 600) // dont log data for next 10 minutes (600 seconds)
// From the DAQFactory Manual: "changing the file name while the logging or export set is running will close the current file and open the new file"
// We change the filename for each new 10 minute interval of data
Logging.DataLog.FileName = "D:\ALT DAQFactory Saves\ALT_" + formatDateTime("%y%m%d_%H%M%S", systime()) + ".csv"
timestamp = systime() // 10 minutes complete - reset timestamp to current system time
saveCount += 1 // 10 minutes completed! - update saveCount
endif
st += scansPerRead / scanRate
backlog = dataIn.ljmscanBacklog
timeLeft = 600 - (systime() - timestamp)
endwhile

I am using custom time formatting on my data logging and it works great! Here's what I've been using %m/%d/%y %H:%M:%S
But if I also wanted to include the milliseconds what is the % for that?
I checked the help, manual, and forum but didn't find anything.
Thanks!
